Minio Client SDK for Haskell Build StatusHackageSlack

The Minio Haskell Client SDK provides simple APIs to access Minio and Amazon S3 compatible object storage server.

Minimum Requirements


git clone

cd minio-hs/

stack install

Tests can be run with:

stack test

A section of the tests use the remote Minio Play server at by default. For library development, using this remote server maybe slow. To run the tests against a locally running Minio live server at http://localhost:9000, just set the environment MINIO_LOCAL to any value (and unset it to switch back to Play).

Documentation can be locally built with:

stack haddock

Quick-Start Example - File Uploader
